March 27. A blank day, as Miss Penclosa goes with Wilson and his wife to the Suttons'. Have begun Binet and Ferre's "Animal Magnetism." What strange, deep waters these are! Results, results, results--and the cause an absolute mystery. It is stimulating to the imagination, but I must be on my guard against that. Let us have no inferences nor deductions, and nothing but solid facts. I KNOW that the mesmeric trance is true; I KNOW that mesmeric suggestion is true; I KNOW that I am myself sensitive to this force. That is my present position. I have a large new note-book which shall be devoted entirely to scientific detail. Long talk with Agatha and Mrs. Marden in the evening about our marriage. We think that the summer vac. (the beginning of it) would be the best time for the wedding. Why should we delay? I grudge even those few months. Still, as Mrs. Marden says, there are a good many things to be arranged. March 28. Mesmerized again by Miss Penclosa. Experience much the same as before, save that insensibility came on more quickly. See Note-book A for temperature of room, barometric pressure, pulse, and respiration as taken by Professor Wilson. March 29. Mesmerized again. Details in Note-book A. March 30. Sunday, and a blank day. I grudge any interruption of our experiments. At present they merely embrace the physical signs which go with slight, with complete, and with extreme insensibility. Afterward we hope to pass on to the phenomena of suggestion and of lucidity. Professors have demonstrated these things upon women at Nancy and at the Salpetriere. It will be more convincing when a woman demonstrates it upon a professor, with a second professor as a witness. And that I should be the subject--I, the sceptic, the materialist! At least, I have shown that my devotion to science is greater than to my own personal consistency. The eating of our own words is the greatest sacrifice which truth ever requires of us. My neighbor, Charles Sadler, the handsome young demonstrator of anatomy, came in this evening to return a volume of Virchow's "Archives" which I had lent him. I call him young, but, as a matter of fact, he is a year older than I am. "I understand, Gilroy," said he, "that you are being experimented upon by Miss Penclosa." "Well," he went on, when I had acknowledged it, "if I were you, I should not let it go any further. You will think me very impertinent, no doubt, but, none the less, I feel it to be my duty to advise you to have no more to do with her." Of course I asked him why. "I am so placed that I cannot enter into particulars as freely as I could wish," said he. "Miss Penclosa is the friend of my friend, and my position is a delicate one. I can only say this: that I have myself been the subject of some of the woman's experiments, and that they have left a most unpleasant impression upon my mind."
